Secrets Store Csi Driver
The Secrets Store Container Storage Interface driver is a Kubernetes storage plugin that enables pods to mount sensitive data from external secret management services directly into container volumes. By utilizing the standard container storage interface, it allows applications to access credentials as files within the file system, ensuring that sensitive information is held in memory rather than persisted to the node disk.
The driver distinguishes itself by providing a unified interface for multi-provider integration, allowing clusters to connect to various external secret management services through a consistent configuration model. It supports automated secret rotation, which triggers updates to mounted files and synchronized cluster objects whenever source data changes in the external provider. To maintain compatibility with existing workflows, the driver can mirror external secret data into native cluster secret objects, enabling applications to consume credentials via standard environment variables or volume mounts.
The project includes comprehensive management capabilities, such as portable configuration definitions and namespace-based access restrictions to ensure security isolation. It also provides observability tools to track the lifecycle and binding status of mounted secret configurations, offering visibility into the specific versions of credentials currently in use by container workloads.
Features
